As I understand it the airbag systems in a modern car are complex, the computer monitors various parameters to stop false triggering and has circuitry which still fires them if power leads are cut during the crash. On my airbag computer a label implies that it has been calibrated for the particular model of car.

Also the airbag deploys with a lot of force, my mate had a number of scratches and abrasions to his face when his deployed. I am thinking it could injure your neck if the airbag shape is not well suited to your cobra.

I have decided to disconnect mine and replace each terminal (2 airbags and 2 seat pretensioners) with a capacitor and resistor to fool the computer that it is all installed, at present it is constantly informing me of a SRS fault...

Be careful when taking out the airbags, they store charge as mentioned above and I think they can still deploy with no apparent power applied.

Air bag's inflate as a result of a reaction of sodium azide (NaN3) with potassium nitrate (KNO3) to produce nitrogen gas which inflates the air bag.
The chemical reaction causes a extremely large volume of gas to inflate the bag up 322kph and inflation is achieved in about 1/25 second.

The airbags in the steering wheel and dash are a real concern(to me) as electrically they are still hooked up to SRS computer with only the sensors disconnected. The SRS computer needs to hooked up to the wiring, if not the car won't start.

I was going to connect the positive and negative wires of the air bags together to stop any spurious voltage spikes, but I am unsure if this would be 100% failsafe method. I was told by a company that sells airbags that if left diconnected that there is virtually no chance of it going off.

What I would like to do is to remove the inflation module completly, but finding anyone that works on airbags is not that easy.
